Filed April 21, 1931 I. z'lziafigm Patented Oct. 4, 1932 PATENT OFFICE DIRK ENNINGA, OF GLENVIL, NEBRASKA TOOL Application filed April 21,

This invention aims to provide a simple means whereby a heating operation can be carried out readily, in connection with corroded battery terminals, soldering, or any other operation.

Itis within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made Within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing:

Figure 1 shows in elevation, a device constructed in accordance with the invent-ion;

Figure 2 is a side elevation of the heating tool, parts being in section;

' v Figure 8 isa transverse section through the head of the heating tool.

The heating tool comprises a handle 1 including an insulating grip 2, made of wood, or any other suitable material, and a metal shank 3, in the form of a rod. The grip 2 has a bore 4, and one end of the shank 3 is secured in the bore. The shank 3, however, does not extend entirely through the grip 2, and, therefore, there exists, in the grip 2, at

the end of the shank 3, a chamber 5, shown in Figure 2. A conductor 6 extends into the chamber 5 and is secured at 7 to the end of the shank 3. The conductor 6 carries a spring clip 8, adapted to grip one of the terminals 9 of a storage battery 10, the other terminal 11 of the battery being engaged by a spring clip 12 on a conductor 14 carrying a spring clip 15. Any source of electrical energy may, of course, be substituted for the battery 10.

The numeral 16 designates a tubular, metal head, arranged transversely of the shank 3, the end of the shank being threaded at 17 into the head 16. Within the head 16, is

1931. Serial No. 531,761.

loosely and removably mounted a tip 18 which may be a piece of carbon pencil, of, the kind formerly used in arc lamps, although the tip may be of any desired form. The tip 18 may be shifted longitudinally in the head 16, as the tip wears away, and the tip is held in any position to which it may have been adjusted by threading the shank into the head 16, until the outer end of the shank bears on the tip, as shown in Figure 2. The tip 18 is of considerably less diameter than the bore of the head 16, as Figure 3 will show.

The device may be used for heating corroded terminals on a battery (not the battery 10, but another battery) or, as shown in Figure 1, the device may be used for soldering. When the device is used for soldering, the clip 15 is engaged with the article 19 to be soldered, and the tip 18 is moved over the article 19, the resistance of the tip 18 to the passage of electrical current causing the tip to become heated.

Having thus described the invention, what is claimed is:

In a device of the class described, a heating tool comprising a shank, a grip on the shank, a tubular head of appreciably greater length than the diameter of the shank and disposed transversely of the shank, the head having a smooth, straight, and continuous bore of greater length than the diameter of the head, and a tip longitudinally adjustable in the head, one end of the shank being threaded into one side of the head, intermediate the ends of the head, and engaging the tip to bind the tip in the bore, at the opposite side of the head, the tip engaging the head throughout the entire length of the head, the tip being of materially less diameter than the bore.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

DIRK ENNINGA.
